version: Update to version 2.1.0

Update to package version V2.1.0 to reflect that a backwards compatible
API change was made. This API change was the introduction of the timeout
to the GET_MBOX_INFO command.

This version update also encompasses previous bug fixes.

The versioning scheme is now aligned to semver.

Use the version from config.h for both mboxd and mboxctl instead of an
independant value for the daemon and control programs.
